SPECIFICATION forming part of LettersPatent No. 355,525, dated January 4, 1887.

Application filed May n, 18st. serial No. 261,8@ (No model.;

To all whom it may cncerm` v VBe it known that I, AUGUsT HEINE, of Sil- Ver Creek,in the county of Chautauqua and State of New York, have invented a new and useful Improvement in Flour-Bolts, of which the following is a specification.

This invention relates to that class of flourbolts which are provided on the inner side of the bolting-cloth with ribs or similar contrivances, whereby the material is elevated until the gradually-increasing angle of the rib causes the material to run off from the rib against'a deflecting board, or strip, which is arranged opposite the inner side of -the elevating-rib, and whereby the material is deflected outwardly, or toward the bolting-surface.

The object of my improvementis to increase the efficiency of this class of flour-bolts, and to render the same simple and durable in construction.

My invention consists, to these ends, of the improvements which will be hereinafter fully set forth, and pointed out in the claims.

In 'the accompanying drawings, Figure yl is a longitudinal sectional elevation of my improved flour-bolt. Fig. 2 is a cross-section of v the same. Fig. 3 is a cross-section of one of the longitudinal ribs and connecting parts on an enlarged scale. Fig. 4 is a fragmentary longitudinal section of one of the end heads of the bolt. Fig. 5 is a fragmentary longitudinal section of the central ring of the bolt.

Like letters of reference refer to like parts in the several figures.

A represents theinclosiug-casing,which may be of any suitable orwell-known construction.

b represents the shaft of the bolt or reel, journaled in bearings B B, secured to the casing A;

C represents the head at the feed end of the bolt, secured to the shaft b, and provided on its outer side with a feed-cone, D, which receives the material to be bolted from a feed-spout, d.

E represents the head at the discharge end 0f the bolt, provided with a central dischargeopening, e, for the tailings, and carrying on its inner side elevating-ribs f and a deflectingcone, f', for discharging the tailings through the opening e, in a well-known manner, into a 5o dischargespout,f2. y

The heads C and E are provided, respectively, with inwardly-turned marginal llanges g g, to which the ends of the bolting-cloth H are secured. Y v

I represents the longitudinal ribs which connect the'heads G and E on the inner side of the bolting-cloth, and which are arranged' at a short distance from the inner surface of the bolting-cloth, so as to leave spaces or passages t' between the outer edges of the ribs and V6o the bolting-cloth, through which the material can pass in owing over the bolting-surface. These spaces are formed by studs or short postsj, which are secured to the outer edges of the-'ribs I, and which carry the ringsfs, 55 againstv which the honing-cloth rests.

Y K'represents the deflecting boards or plates arranged opposite the inner edges of the ribs I, and separated therefrom by spaces or passages It, through which the material flows from 7o one rib to the rib neXt below. These spaces are formed by studs or short posts l, which are secured to the inner edges of the ribs I, and to which the deilecting-plates K are secured by bolts m. The latter pass, preferably, 7 5 also through the studs j and rings f3, as represented inlFig. 3, thereby securing all of these parts to the ribs I.

N represents inclined fan-blades secured to the shaft b -within the reel, preferably near 8o the discharge-head E, and inclined sharply to the axisofrotation in such manner as to cause a slow movement of the air through the reel from the feed end to the discharge end thereof, thereby assisting in the removal of the light floatingspecks, &c., through the dischargeopening e-of the head E.

The boltiug-cloth H is composed of two sections, h h', secured with their outer ends respectively to the heads Gand E, and with their inner ends to the central ring, J,which is made somewhat wider than the rings f3, for the purpose of securing the bolting-cloth. The ring J is provided with two peripheral rows of sharp-pointed teeth or pins, oo, towhich the bolting-cloth sections h h are attached ,by fast ening the strips p p', of ticking or other strong material, on these'pins, as represented in Fig.

5. These strips are provided with cords q q',

which are sewed between two thicknesses of IOOV the strip, which latter are doubled back to receiye the cords, whereby the cords are located outer sides with rings tt, of leather or other at the extreme inner edges of the sections h h, and serve to re-enforce these edges. In applying thestrips 19p to the teeth o o the cords are placed on the inner sides of the rows of teeth, so that the strain which is applied to the bolting-cloth in stretching the same tends to draw the cords against the teeth, thereby securely holding' the strips in place on the ring J. The outer edges of the sections i h h are also respectively provided with strips r 1", of ticking or other strong material, which are fastened to the heads C and E by tacks s after the cloth has been properly stretched. When the heads C and E are constructed of metal, the flanges g g of the same are provided on their suitable material, into which the tacks can be driven.

The material which is being bolted is elevated in part by the ribs I and gradually discharged by the same against the deiiectingplates K, and passes from these to the ribs I below, and then against other defiecting-plates K, whereby the material is broken up, disintegrated, or dashed in such manner as to liberate the light iiutfy impurities, while the heavier particles pass in comparatively thin streams through the spaces and k, opposite the outer and inner edges of the ribs, and over the bolting-cloth, whereby the operation of bolting is greatly facilitated and expedited. The light floating impurities pass through the spaces between the deflecting-boards K, into tlie inner space of the reel,which is comparatively undisturbed, and in which they pass slowly toward the discharge-opening e, through which they finally escape from the reel. This movement ot' the floating material in the direction of the axis of the reel is toa large extent due to the action of the inclined fanblades N, which cause a gentle air-current to pass through the reel in the direction of its length and insure the removal of the floating impurities.

I claim as my invention- 1. In a rotary Hour-bolt, the combination, with the bolting-surface H, of the elevatingribs I, separated by spaces t' from the boltingsurface, and defiecting-plates K, arranged cpposite the inner edges of the ribs I, separated therefrom by spaces k, and constructed with unobstructed outer faces opposite the elevatingrib, whereby the material is enabled to pass freely from an elevating-rib to its deectingplate, and from the latter to the elevating-rib below, substantially as set forth.

2. In a rotary ilour-bolt,the combination, with the bolting-surface H, of the elevatingribs I, provided on the inner edges with studs Z, and separate deflecting-plates K, secured to said studs, whereby spaces are formed between the plates K and the elevating-ribs, as Well as between the several detiecting-plates K, substantially as set forth.

3. In a rotary flour-bolt, the combination, with the bolting-surface H, of the elevatingribs I, provided on their outer edges with studs j, upon which the bolting-surface is supported, and on their inner edges with studs Z, separate detlectingplates K, applied to the studs Z, and fastening-bolts m, passing through the ribs I, studs j and Z, and detlecting-plates K, substantially as set forth.

4. The combination, with a rotary flour-bolt, of short fan-blades inclined sharply to the axis of rotation, secured within the bolt and rotating therewith, whereby an air-current is caused to flow lengthwise through the'bolt, substantially as set forth.

5. The combination, with a rotary flour-bolt provided with longitudinal elevating-ribs I and deflecting-plates K, of inclined fau-blades secured within the bolt, substantially as set forth.

6. The combination, with a rotary flour-bolt composed of a shaft, b, heads C E, elevatingribs I, deliecting-plates K, andabolting-cloth, H, of fan-blades N, secured to the shaft b between the heads C and E, substantially as set forth.

7. The combination, with a rib, I, of the studs j and Z, applied, respectively, to the outer and inner edges of said ribs, a ring, f3, resting on the outer stud, j, a deflecting-plate, K, resting against the inner stud, Z, and a fasteningbolt, rm., passing through the ring f3, stud j, rib I, stud Z, and plate K, substantially as set forth.

8. The combination, with the end heads, C and E, and the central ring, J, provided with two peripheral rows, o o, of sharp pins, of two sections of bolting-cloth, h h', having their inner edges re-enforced and attached to the pins o o and their outer edges tacked to the heads C and E, substantially as set forth.
